Parnelli VPJ1
The Parnelli VPJ1 is an open-wheel race car, designed by British designer and engineer Maurice Phillippe for Vel's Parnelli Jones Racing, to compete in U.S.A.C. Championship Car for 1972. It was driven by Mario Andretti, Al Unser, and Joe Leonard. It was powered by an Offenhauser four-cylinder turbo engine, reputed to develop between , depending on turbo boost pressure levels. In its original configuration, the car was designed with dihedral wings mounted to either side of the cockpit and sticking up at 45-degree angles. However, the unusual aerodynamic design proved no performance benefits, and by the Indianapolis 500 in May, the design had been revised to have the wings removed. Following the redesign, the car saw success, most notably with Joe Leonard who won three races and won the 1972 USAC Championship. Al Unser and Mario Andretti Mario Gabriele Andretti (born February 28, 1940) is an Italian-born American former racing driver. One of the most successful drivers in the hi ...

Dihedral (aeronautics)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turbo
In an internal combustion engine, a turbocharger (often called a turbo) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake gas, forcing more air into the engine in order to produce more power for a given displacement. The current categorisation is that a turbocharger is powered by the kinetic energy of the exhaust gasses, whereas a is mechanically powered (usually by a belt from the engine's crankshaft). However, up until the mid-20th century, a turbocharger was called a "turbosupercharger" and was considered a type of supercharger.

1972 USAC Championship Car Season
The 1972 USAC Championship Car season consisted of ten races, beginning in Avondale, Arizona on March 18 and concluding at the same location on November 4. The USAC National Champion was Joe Leonard and the Indianapolis 500 winner was Mark Donohue. Jim Malloy was killed at Indianapolis in practice; he was 40 years old. After sponsoring the USAC Championship Trail in 1970-1971, Marlboro dropped out of the sport for 1972. After only two seasons as title sponsor, the company became angered when rival Viceroy was signed on to sponsor Vel's Parnelli Jones Racing, at the time dubbed the "super team" of the series. Without any exclusivity clause, managers at Marlboro deemed the situation "impractical and untenable," and abruptly quit. Marlboro would not return to Indy car racing until 1986. Schedule and results All races running on Oval/Speedway. : Originally scheduled for July 2, postponed because of rain. In the fall of 1971, a tentative schedule held the possibility of retur ...

List Of USAC Championship Car Seasons
From 1956 to 1978, USAC Championship Car seasons featured the top teams and drivers in U.S. open-wheel racing. Until 1971, the Championship contained road courses, ovals, dirt courses, and, on occasion, a hill climb. Thereafter, the schedule consisted mainly of paved ovals. In 1979, the majority of car owners left USAC to race in the Indy Car World Series, sanctioned by the Sports Car Club of America and CART. This led to a decline in the number of events in the schedule, and by the 1984-85 season, the Championship comprised only one race, the Indianapolis 500. The era of USAC Championship Cars concluded with the formation of the Indy Racing League (IRL) in 1995, which was sanctioned by USAC until June 1997 when the IRL assumed officiating duties after the controversial finish of the 81st Indianapolis 500 and the scoring mistake that marred the following event. The most successful driver in USAC Championship Car history was A. J. Foyt with seven National Championships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Race Car
Auto racing (also known as car racing, motor racing, or automobile racing) is a motorsport involving the racing of automobiles for competition. Auto racing has existed since the invention of the automobile. Races of various sorts were organised, with the first recorded as early as 1867. Many of the earliest events were effectively reliability trials, aimed at proving these new machines were a practical mode of transport, but soon became an important way for automobile makers to demonstrate their machines. By the 1930s, specialist racing cars had developed. There are now numerous different categories, each with different rules and regulations. History The first prearranged match race of two self-powered road vehicles over a prescribed route occurred at 4:30 A.M. on August 30, 1867, between Ashton-under-Lyne and Old Trafford, a distance of eight miles. It was won by the carriage of Isaac Watt Boulton. Internal combustion auto racing events began soon after the construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open-wheel Car
An open-wheel single-seater (often known as formula car) is a car with the wheels outside the car's main body, and usually having only one seat. Open-wheel cars contrast with street cars, sports cars, stock cars, and touring cars, which have their wheels below the body or inside fenders. Open-wheel cars are built both for road racing and oval track racing. Street-legal open-wheel cars, such as the Ariel Atom, are scarce as they are often impractical for everyday use. History American racecar driver and constructor Ray Harroun was an early pioneer of the concept of a lightweight single-seater, open-wheel "monoposto" racecar. After working as a mechanic in the automotive industry, Harroun began competitive professional racing in 1906, winning the AAA National Championship in 1910. He was then hired by the Marmon Motor Car Company as chief engineer, charged with building a racecar intended to race at the first Indianapolis 500, which he went on to win. He developed a revolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Firestone Tire
Firestone Tire and Rubber Company is a tire company founded by Harvey Firestone (1868–1938) in 1900 initially to supply solid rubber side-wire tires for fire apparatus, and later, pneumatic tires for wagons, buggies, and other forms of wheeled transportation common in the era. Firestone soon saw the huge potential for marketing tires for automobiles, and the company was a pioneer in the mass production of tires. Harvey Firestone had a personal friendship with Henry Ford, and used this to become the original equipment supplier of Ford Motor Company automobiles, and was also active in the replacement market. In 1988, the company was sold to the Japanese Bridgestone Corporation. History Early-to-mid-20th century Firestone was originally based in Akron, Ohio, also the hometown of its archrival, Goodyear, and two other midsized competitors, General Tire and Rubber and BFGoodrich. Founded on August 3, 1900, the company initiated operations with 12 employees. Together, Firestone ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
